Today do 5s open a custom camera when framing does not have full screen issues such as Add the following code to resolve the issue to turn viewfinder into full screen { CGSizescreenBounds=[UIScreenmainScreen].bounds.size; CGFloatcameraAspectRatio=4.0f/3.0f; cgfloatcamviewheight= screenBounds.width*cameraAspectRatio; CGFloatscale=screenBounds.height/camViewHeight; pickerController.cameraViewTransform= Cgaffinetransformmaketranslation (0, (screenbounds

almost all digital cameras have an LCD LCD screen. The LCD's English is all called Liquid Crystal Display. Its role is mainly to browse pictures and framing. Some ultra-thin digital cameras now almost omit the optical viewfinder, leaving only the LCD screen.The main technical parameters of the LCD screen are the size of the display and the dimensions of the pixel. Dimensions are measured in inches, such as 1.8-inch, 2.0-inch, 2.5-inch, and so on. The

digital camera, it is very easy, that is, to multiply the pixel. 11. Action-stopping Rule) This rule is based on empirical formulas of angle and speed. If you can capture an object along the axis of the lens with a 1/125 shutter, it can capture the motion of the axis of the lens in 1/500 seconds. That is to say, if an object is known as 45 degrees of motion along the axis of the lens, the shutter speed is only 1/250. 12. Sunset Rule) When shooting the sunset, measure the light in the upper part
